HVAC Constant Air Volume

When choosing a HVAC college program, the most important point that you must find out is that the choice of college you have selected is an accredited one. This is ultra important, as it means that the training program provided will be at least as good as specified by approved HVAC organizations.

The premier accrediting agency for HVAC training programs is the NCCEA, which is the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. Select a college that has a minimum of at least one accreditation.

Smaller class sizes are also important, which means you will get one to one tuition from the instructors. The best colleges teaching HVAC courses will also have an onsite science lab with professional-grade tools. Before enrolling make sure you visit and explore the campus and get a feel of the place, the teaching areas, the facilities available and talk to the teachers, if possible. You should also find out whether there is any flexibility in time-managing classes for working students, and how you should go about procuring financial aid, if you are eligible.
